Two-staged Merlin Spitfire production 1942-1945

[Kurfürst]

Hi,

I just finished a producion analysis of mine, using individual aircraft records within Spitfire : The History as a base source.

The following graph give a color representation of the production of Spitfire fighter Marks, with two-staged Merlins, between 1942-45.

I used different colours to make it easier to differentiate between various Marks, using the engines optimum band of operation (ie. high or low altitude engine) as a basis, and shades of that color to differentiate between similiar Marks (VII, VIII, IX) using the same engine.

Given the considerable amount of time spent on creating and processing this database, you are free to use this graph or parts of it as you wish, but if you do so, I`d like to be given the credits for it, by referring to my usual login (Kurfurst) and the URL of my website (its also imprinted on the graph).
